1253634 - Figure out why idbfactory_open9.htm errors

Status: RESOLVED DUPLICATE of bug 1275496

(Core :: Storage: IndexedDB, defect)

Description

[:Ms2ger (he/him; ⌚ UTC+1/+2)]

It claims there's an uncaught exception from inside the function passed to async_test, which shouldn't be possible.

Comment 1

[James Graham [:jgraham]]

The line that seems to be throwing is 52 (or, at least one of the lines):
var rq = window.indexedDB.open(dbname, val);

which throws AbortError. It seems from the spec like these steps might be run async, so the error is caused by this code but not actually thrown inside the try/catch block. Which is pretty funky.

I'm putting "-fixlater" here since this doesn't seem like a super-critical "-fixnow" but seems more important than a "we'll get to it some day" "-backlog".

More analysis is summarized in bug 1275496 comment 2.
In short, this failure is caused by the overloading function of |IDBFactory.open(name, IDBOpenDBOptions)| and the signature change of |IDBFactory.open(name, version)| done in bug 785884.
